The parliament held a confidence vote on Sunday during which it reaffirms Mr. Zangeneh's stay in office in President Rouhani's second term.

The lawmakers cast 230 votes for Rouhani's pick for petroleum ministry and 35 against votes.

The legislature started debating the credentials of the 17 nominees on Tuesday. The debate continued on Wednesday and Thursday, and then on Saturday, Presstv reported.

The entire proceedings were broadcast live in the Iranian national TV as it was demanded by the parliament.

Rouhani won re-election back in May. He took the oath of office earlier this month after being formally endorsed as the Iranian chief executive by Leader of the Islamic Revolution Ayatollah Seyyed Ali Khamenei.
